What this Trial Is About
This study aims to explore the effects of anxiety traits on pain, anxiety, and anesthesia satisfaction in patients undergoing cataract surgery under topical anesthesia. On the day of recruitment, patients will complete the BAI, STAI-S, and STAI-T anxiety questionnaires to assess baseline anxiety levels. Thirty minutes before the surgery, patients will be randomly assigned, in a double-blind manner, to receive either Xanax or a placebo and will retake the BAI, STAI-S, and STAI-T questionnaires. After the surgery, patients' pain levels and anesthesia satisfaction will be evaluated, with the pain scale and satisfaction survey repeated the following day. The results will analyze the relationship between anxiety traits and pharmacological interventions on the surgical experience, aiming to optimize surgical procedures and improve overall patient comfort.
